(a) Field of the Invention
The present invention relates to a backpack structure combined with pull-carrier device, and more particularly to a bag device having application to facilitate a user to pack and transport articles, and a configuration provided with spatial transformation for retaining of articles therein and multifunctionality to accommodate different uses.
(b) Description of the Prior Art
Conventional carrying devices for loading articles that provides for transporting the goods at the same time as when a person is walking basically include handbags, backpacks or suitcases provided with an extensible bar that enables pulling of the suitcase.
Referring to
(1) Wheeled suitcases (bags) that can be pulled along the ground for transporting articles are mainly designed with the objective for loading and transporting relatively many belongings or articles, and even if they are configured with a transformation space function, the transformation space they are able to produce is limited, and is still confined to the range of large-scale transportation carrying devices. If such carrying devices are carried on the back, the shoulders or by hand, then it will inevitably result in the body having to bear the hardship of carrying a heavy load.
(2) Carrying devices that are carried on the shoulders or by hand are mainly designed with functionality for carrying simple and convenient articles for daily use. However, because the objectives of the carrying devices are lightness and portability, thus, there is no need to consider the additional configuration of wheels for pulling along the ground for transporting articles.
(3) Carrying devices that are carried on the back have functionality between the two aforementioned carrying devices. Because of the method of carrying on the back, thus, a weight load is balanced on the body and does not require strenuous effort to carry. Hence, recent years have seen widespread use of such carrying devices when hiking, going on an outing or journey, or daily travel. However, back carrying devices on sale in the current market are not provided with an adequate transformation holding space configuration. Such types of products still merely consider the needs of specific users. For example: use when hiking or traveling requires a carrying device with large capacity, whereas use for daily travel requires a carrying device with small capacity. The main reasons for the difficulty in making a breakthrough in the original design of current conventional products lie in: (a) inability to effect large area transformation of holding space, (b) a wheeled pull-carrier device, when configured on the back carrying side, results in contact with the back of the body that causes uncomfortableness, (c) when pulling a wheeled pull-carrier device along the ground to transport articles, possible dragging long the ground of sagging straps results in soiling thereof.
In light of the shortcomings of conventional prior art products, the present invention has made a breakthrough in design and provides a carrying device that is able to achieve a multiplicative variation in the space for retaining articles and stowage capacity, and is characterized in providing a multifunctional combined configuration which enables a person to carry the device on the back, the shoulders, by hand or pulled on wheels. Furthermore, at the same time resolves the shortcomings of uncomfortableness to the user when carrying on the back, sagging of straps when pulling along the ground to transport articles, and so on.
SUMMARY OF THE INVENTIONA primary objective of the present invention is to provide a backpack structure combined with pull-carrier device, wherein transformation portions provided with spatial transformation functionality are respectively connected to left and right sides or an upper side of a basic bag, thereby providing a stowage device that can be carried on the back and achieve an multiplicative increase or decrease in the space for retaining articles and stowage capacity.
Another objective of the present invention is to provide the backpack structure combined with pull-carrier device, wherein a wheeled pull-carrier device is disposed on a juxtaposed side of a back carrying side of the basic bag using a detachable movable method. When the basic bag is expanded and holds many articles, then a wheel portion configured to the pull-carrier device can be used to pull the backpack along the ground to transport the articles. When the goods to be transported are of excessively large size, then the pull-carrier device can be separated from the basic bag and used to carry and transport the goods.
A fourth objective of the present invention is to provide the backpack structure combined with pull-carrier device, wherein a top portion of the basic bag is configured with a top cover structured from a combination of an inner strip, a plurality of outer strips and top contracting members. Each of the plurality of outer strips is configured with a notch portion and radially arranged on the upper surface of the inner strip, thereby forming a first transformation area between the plurality of outer strips and the inner strip to achieve expanding and contracting functionality of the top cover. Furthermore, combination of the notch shapes from each of the notch portions enables forming a variation of patterns.
A fifth objective of the present invention is to provide the backpack structure combined with pull-carrier device, wherein the basic bag is configured with a bottom portion and a bottom contracting member.
To enable a further understanding of said objectives and the technological methods of the invention herein, a brief description of the drawings is provided below followed by a detailed description of the preferred embodiments.
Referring to
An expanded bag body 10 (largest holding space) is formed after extending the two transformation portions 2, 3, and male and female mutually corresponding joining sides 22, 32 are located on same side corresponding angle ends of the transformation portions 2, 3 respectively. Referring to
Regarding contraction of the present invention to reduce capacity thereof, a manual pulling method can be used to pull and fasten together the male and female juxtaposed joining sides 22, 32 located on angle edge lines 21, 31 formed by the transformation portions 2, 3, thereby achieving the objective of contracting the basic bag 1 using a method such as zip fasteners.
Furthermore, the basic bag 1 is provided with the pull bar 4 on one side of the correspondingly positioned joining sides 22, 32, and the pull bar 4 can be covered by a covering body 41 and positionally fixed therewith. The pull bar 4 is configured with exposed ground-contacting wheels 42 close to position of a lower angle end 11 of the basic bag 1. The pull bar 4 is an extensible structure, which can either comprise two rods joined to form a squared-off inverted U-shaped configuration, as depicted in the drawings of the present invention, or a single rod extensible pull bar can be used (not shown in the drawings). When the two joining sides 22, 32 are joined, the aforementioned pull bar 4 and covering body 41 are in a state enveloped by the two joining sides 22, 32.
An inner side surface of the basic bag 1 covered by the covering body 41 upwardly extends from the position of the ground-contacting wheels 42 and is situated between the pull bar 4 and the basic bag 1, thereby forming an interlayer 140 that provides for holding thin-shaped articles therein. Juxtaposed fastening members 141 can be located on an inner side of the interlayer 140 to enable fastening together and formation of a sealed inner side.
Implementation of the inner side juxtaposed fastening members 141 can be used to directly connect to position vacated by a handle 40 of the pull bar 4 at a head end 50 of the top cover 5 located on the basic bag 1. However, if an upper portion of the covering body 41 is directly connected to the top cover 5, as depicted in the embodiment of
Furthermore, direct connection of the top cover 5 to the upper end of the covering body 41 can be used to enable simultaneous closing over of the interlayer 140 and the handle 40 of the pull bar 4 and the opening 12 of the basic bag 1.
Joining methods for joining the periphery of the opening 12 to the top cover 5 include using hook and loop fastener strips located on the periphery of the opening 12 and the corresponding periphery of the top cover 5, or buttons or a zip fastening method can be used to fasten the two together, and because such joining methods are known from prior art, thus, they are not described hereinafter. The transformation portions 2, 3 are made form flexible material, such as cloth material, which is easily transformed through manual operation. The transformation portions 2, 3 are structured to comprise five surrounding sides, primarily from first side surrounding sides 211, 311, second side surrounding sides 212, 312 and third side surrounding sides 213, 313 to surround and form inverted squared-off U shapes, upper and lower ends of each of which are enclosed with top sides 214, 314 and bottom sides 215, 315 respectively, and corresponds to an open connecting central interior space formed by connecting sides of the basic bag 1. The transformation portions 2, 3 joined to the basic bag 1 form box-shaped holding spaces provided with an opening that enables access to the entire interior.
During the operating process of contracting the present invention, apart from plane transformation of the first side surrounding sides 211, 311, the second side surrounding sides 212, 312 and the third side surrounding sides 213, 313, moreover, synchronized transformation of end sides of the top and bottom surfaces 214, 314, 215, 315 also occurs. Because transformation of the four end surfaces is as a result of using flexible material, thus, tolerance range of the transformation is enormous. Hence, during the process of contracting the basic bag 1, there is practically no need to take into consideration transformation state of the top surfaces 214, 314 and the bottom surfaces 215, 315, such as kinking and piling.
Referring to
Operating steps include first pulling the joining side 22, 32 towards one side of the basic bag 1 in a central direction, whereby, during the process of pulling, the first side surrounding sides 211, 311 contract towards the center, which simultaneously moves in coordination the second side surrounding sides 212, 312 and the third side surrounding sides 213, 313, thereby producing a displacement transformation.
